Title: Method for producing flame retardant porous products and products produced thereby
Inventor: SALYER IVAL O
IPC: E04B1/94
Filed: 1998-05-26
Abstract: A method for fire retarding porous products used for thermal energy storage and products produced thereby is provided. The method includes treating the surface of the phase change material-containing porous products with a urea fire-retarding agent. Upon exposure to a flame, the urea forms an adduct with the phase change material which will not sustain combustion (is self-extinguishing) in air. No halogens or metal oxides are contained in the fire retardant, so no potentially noxious halide smoke or fumes are emitted if the product is continuously exposed to a flame.

Title: Electrode structure and method of making for ferroelectric capacitor integrated on silicon
Inventor: RAMESH RAMAMOORTHY
IPC: H01L27/04
Filed: 1996-12-17
Abstract: A ferroelectric capacitor structure and its method of making in which a ferroelectric stack of two metal-oxide electrodes (46, 52) sandwiching a ferroelectric layer (50) is fabricated on a silicon substrate (40) with an intervening barrier layer, preferably of TiN (42). In one embodiment, a platinum layer (44) is grown between the TiN and the lower metal-oxide electrode at a sufficiently high temperature that provides crystallographically ordered growth of the ferroelectric stack. In another embodiment, the platinum layer was completely eliminated with the lower electrode (46) being grown directly on the TiN (42). Although the conventional conductive metal-oxide used in the electrode is lanthanum strontium cobalt oxide (LSCO), lanthanum nickel oxide provides good electrical and lifetime characteristics in a ferroelectric cell. Alternatively, the electrodes can be formed of the rock-salt metal oxides, such as neodymium oxide (NdO).

Patent CA-2241986-A1 (CA)
Inventor: KARPENKO EVGENY IVANOVICH
IPC: F23C5/00
Filed: 1996-01-03
Abstract: The invention is in the field of power engineering and can be used in thermal power plants to fire up boiler units without using fuel oil from a cool state to a working regime. The aim is to eliminate the need for fuel oil for firing coal-dust torches, thereby enhancing the efficiency of the boiler firing process. The proposed technology for firing industrial boilers without fuel oil is based on plasma fuel ignition techniques. A successful result is achieved when the coal-dust torch is fired by generating a stream of low-temperature plasma using plasma generators installed in the muffles of the lower-tier coal-dust burners, feeding the coal-dust mixture through the low-temperature plasma stream and igniting it and by subsequent switching off of plasma generators. In addition, depending on the type of boiler unit, pulverisation techniques and fuel characteristics, the quantity (n) of coal-dust burners equipped with plasma generators and muffles can be in the range of n = 1  m, where m is the quantity of burners on the lower tier.

Patent CA-2260795-A1 (CA)
Title: Synthetic protein folding catalysis
Inventor: RAINES RONALD T
IPC: C12N9/90
Filed: 1997-07-09
Abstract: An analysis of the protein folding characteristics of the eukaryotic protein folding enzyme protein disulfide isomerase (PDI) led to a study of the minimally sufficient motif for catalytic activity of that enzyme as well as the prokaryotic enzyme thioredoxin. Based on such study, a model for this catalytic activity was developed which was used to predict what non-protein catalysts might substitute for this enzymatic activity. Based on this analysis, it was predicted that a small molecular weight dithiol molecule having a pK a of less than about 8.0 and an E~' of more than about-0.25V could catalyze the formation of proper disulfide bonds in a eukaryotic protein. Subsequently, it was verified that such a dithiol, such as the exemplary molecule BMC, is capable of catalyzing the proper formation of disulfide bonds, and the proper folding of proteins, both in vivo and in vitro. This permits a small organic molecule to be substituted for an enzymatic system in protein synthesis.

Title: Method or producing naphthyridine compounds and novel intermediate products

IPC: C07D213/61
Filed: 1997-10-17
Abstract: An advantageous method of producing naphthyridine compounds of formulae (Ia) to (1c) wherein R means hydrogen or C1-C4 alkyl, Ar means possibly substituted phenyl, Hal means independently fluorine, chlorine or bromine, and n stands for 1, 2 or 3, whereby a halogenated nicotinic, isonicotinic or picolinic acid is made to react with an amino acrylic acid ester to obtain a halogenated 2nicotinoyl-, isonicotinoyl- or picolinoyl-3-aminoacrylate which is made to react with an optionally substituted aniline to obtain a halogenated 2nicotinoyl-, isonicotinoyl- or picolinoyl-3-aminoacrylate which contains an amino group corresponding to the optionally substituted aniline.

Patent CA-2279626-A1 (CA)
Title: Method and apparatus for estimating pilot coverage
Inventor: WU XIAO CHENG
IPC: H04B7/005
Filed: 1999-08-04
Abstract: A method and system that minimizes pilot signal overlap and radio frequency ("RF") interference by estimating changes in pilot coverage for different traffic channel loading and ower conditions. Once base stations are positioned, a terminal for measuring received pilot signal strengths, such as a mobile station or pilot scanner, is used to collect and generate the baseline pilot survey data, which is then stored on a disk or tape. Base station transmit pilot Ec/I o s, i.e., traffic channel loads on forward links, are also stored on disk or tape. The invention uses two adjustment factors associated with transmit power and traffic channel loading to optimize for different RF  conditions, specifically for different base station transmit power or forward link loading conditions. For each RF condition, the methodology calculates the changes in the baseline pilot survey data. This reflects what Ec/I o s a mobile station would receive under the given conditions. The systems engineer collects a set of optimized base station power settings for each of the different traffic channel load conditions. One of these optimized power settings is then selected by the systems engineer for each of the base stations.

Title: A medical consultation management system
Inventor: FALCHUK KENNETH H
IPC: G16H10/60
Filed: 1998-03-13
Abstract: A medical consultation support system in which a client computer, such as a personal computer or a terminal of an existing medical support system, is employed to transfer a structured request for consultation from a primary care physician to a supervisory host computer. The structured request may be accompanied by additional information related to the request, such as existing data files containing patient history information, medical image data, laboratory results, pathologies, etc., forming a transmittable, machine-readable collection of information relating to the consultation request. At the supervisory computer, the request is displayed for preliminary review by a receiving staff physician who designates a specialist and retrieves and assembles selected tutorial and background information, including related published articles, tutorial background lessons, practise and protocol documentation, and records of prior consultations which are related to the current consultation request, all of which are stored in one or more databases of medical information accessible to the supervisory host computer. The supervisory computer then transmits the request for consultation, together with at least the identification of the assembled supporting documentation, to the selected specialist for review, and thereafter receives the responsive comment from the selected specialist. The supervisory computer further stores the request for consultation, including the specialist's responsive comment and an indentification of the cited supporting material, as a structured case history item in the database of medical information where it may be accessed for future reference. Each consultation is further stored as a recorded learning event associated with the requesting primary care physician, and used to generate a report of continuing legal education credits earned by the requesting physician while participating in the managed consultation sessions.
